To whom it may concern:
Please find a small code example which causes an internal compiler error with
g++-4.7 (opensuse):
Best regards,
Andreas Karrenbauer
$ cat bug_g++.cc
auto foo = [&](int a) { return a > this->b; };
int main() { return 0; }
$ g++-4.7 -v -Wall -g -std=c++0x bug_g++.cc -o bug_g++
